Protective Suit Straps in Channels for Impact Damping

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing safety suits disrupt work activities due to protruding straps, and they fail to effectively dampen impact forces during falls, compromising user safety and comfort.

Innovation Solution

The safety suit features straps arranged predominantly within individual channels on the front of the overall, preventing them from protruding and providing a friction effect that reduces impact forces, with adjustable channels and connecting devices for optimal fit and ease of use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If straps are arranged on the front of the overall, then the user is securely held and caught, but the straps protrude and disrupt work activities

Engineering Contradiction:

Improvesafety functionVSAvoidwork freedom

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements channels that receive and contain the straps, allowing the straps to be nested within the channel structure rather than protruding outward. This resolves the contradiction by maintaining the straps' safety function while eliminating their disruptive protrusion during work activities.

Inventive Principle:

Principle #7Nested doll (Nesting)

Solution Approach 2:

The channels act as an intermediary element between the straps and the outer surface of the overall. The channels provide a pathway that guides the straps while preventing them from protruding, thus mediating between the need for secure strap attachment and the need for unobstructed work space.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If straps are securely sewn to the overall, then the user is held securely, but impact forces during falls are not effectively dampened

Engineering Contradiction:

Improvesecure attachmentVSAvoidimpact shock

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent incorporates friction-based damping within the channel structure that activates during falls. The channels are designed to create friction against the straps, providing cushioning effect beforehand and during impact, thus reducing the harmful shock forces while maintaining secure attachment during normal use.

Inventive Principle:

Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The patent converts the potentially harmful impact forces into beneficial friction effects. During falls, the straps interact with the channel walls through friction, which dissipates the impact energy and reduces the shock transmitted to the user's body, thereby converting the harmful impact into a protective damping mechanism.

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

3Reliability

If additional straps and fastening rings are provided, then the user is held securely, but the device complexity increases and work is disrupted

Engineering Contradiction:

Improvesecure holdingVSAvoidnumber of components

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the functions of multiple straps and fastening rings into an integrated channel system. The channels consolidate several strap pathways and attachment points into a unified structure, reducing the number of separate components while maintaining the secure holding function.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The channels serve multiple functions simultaneously: they guide the straps, prevent protrusion, provide friction-based damping during falls, and offer structured attachment points. This multi-functionality reduces the need for separate dedicated components for each function, thereby reducing overall device complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Applied Scientific Principles

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.

Function Achieved in This Case

This design ensures undisturbed workspace, reduces disruptive forces during work, and provides a softer catching mechanism in case of falls, while allowing for easy adjustment and maintenance, ensuring user safety and comfort.

Implementation Method 1

an additional friction effect is achieved by guiding the individual straps within the individual channels, which means that in the event of a possible fall and the associated catching of the body, the forces acting on the user can be reduced and thus dampened
